vmm'rmo SYSTEM Application filed September Toall wkomit may com-em Be it known that I, Manama E. SKINNY-1R, a. citizen of the United States, and a resident of Wilkinsbiirg. in'the county of Alle- 5 gheny and State of Pennsylvania. have invented a new and useful Improvement in Ventilating Systems for Reactance Coils, of which the following is a specification.

My invention relates -to ventilating devices, and it has particular relation to the ventilation of reactance coils and the like. One of the objects of my invention is to provide a device of the character described wherein a cooling air current may be so directed and didmbuted as to come into contact with all of the heated rtions of the coils at points where it" will ave the greatest efi'ect.

Another object of my invention is to rovide an arrangement of batlle plates or liarriers that may b'easily and quickly applied to a reactancecoil without materially changing the structure thereof.

With such objects in view, as well as other advantages which may be incident to the use of the improvement. the invention consists in the parts and combinations thereof hereinafter setforth and claimed. with the understanding that the several necessary elements constituting the same may be varied in proportion and arrangement with out departing from the nature and scope of the invention.

In order to make the invention more clearl v understood. there are shown in the accom panying drawings means for carrying the same into practical efi'ect. without limiting the improvements. in their useful applications, to the particular constructions which, for the purpose of explanation, have been made the subject of illustration.

n the accompanying drawings,

Figure'l is a vertical longitudinal sectional view through a. reactance coil illustrating'an embodiment of my invention.

Figure 2 is a plan view. with parts broken away, of the structure illustrated in Figure 1.

Figure 3 is a view similar to Fig. l illustruting a modificd form of my invention.

Figure 4 is a plan view with p'arts broken away. of the structure illustrated in Fig, 3.

Referring to the drawings:

A rcactance coil of any prcfcrred construction is shown as comprising a plurality 1,4qs,2s3 PATENT orric'ti.

plate or disk 5 which covers "the top of the coil.

The structure is supported by legs or pedestals 6 of insulating material and construction and over an opening 7 in the floor, through which a current of cooling air is forced from a suitable blower or fan, not shown. 4

Referring to Figures 1 and 2 0f the drawinns. a cylindrical barrier 8 is so disposed adjacent the bottom of the structure as to surround the legs 7 and extends from the floor to the lower portion of the coil structure and completely encloses the sp ce between the bottom of the coil and the floor.

By this arrangement, all of the air iwiing from the opening 7 is directed upwardly through the coils and esca pcs radially at the sides thercofbctwccn the radially extending supporting and retaining members 2. The air is prevented from passing vertically upwardly through the chamber' 3 and passing out at the top of the coils structure by means of the plate 5 which deflects the current downwardly and outwardly through the heated coils in a radial direction.

In Figs. 3 and 4, I have shown a modified form of my invention in which the upper end of the ch'amhcr 3. only. is closed by the central plate 5'. A cylindrical barrier 8' extends from thc floor to the upper extremity of the coil and entirely encloses the same.

By this lattcr arraugcmcnt. the air is dircctcd upwardly through the coils and escapes at the top thereof.

. -I claim as my invcntion:

1. A rcactance coil comprising: a coil. supporting moans thcrel'or. a barrier surrounding said supporting mcaus and terminating' adjacent to the Iowcr portion of said (011 to form an air charhhcr thcrcbcncath and a balllc plutc disposcd at the top of the coil for dcflcvliug an air rul'rcut through said coil in a radial direction.

2. A rcactance coil romprising a (nil hav ing: a centrally disposed air r'orr aml a hafllr plate ilisposell mljarrnt to tho upper portion of Slllll rail for ilr-flrrtiug an air cur- 5 rent through saixl coil in a substantially rarlial direction.

3. A rractam'e (oil com n'isingg a coil ha ing a centrally (lisposml air con. and a haflle plate closing the upper portion of Sillll 10 air core for deflecting a rurront of air in a substantially radial (lll(('tl(lll lwtwrvn the respective conrolutions of said coil.

4. A reactance (oil (-omprisin; a rail liar ing a centrally disposed aircore, upporting members for sairl coil. :1 harrir surrounding saiil supporting means to provide an air chamber hem-nth said coil. and 8. baffle plate for rlosing the upper portion of 'a'id air Corr for deflecting a curlrnt of air in a suhstantiallv radial (lirrrtion be- L noath tho rrspcctim convolution of sairl coil.

In trstimony whereof. I have hereunto suhscrihml my name this 3 th (lay of August. 1920.
